NS ANTARCTIC against its type

Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,372 gross tonnage it is larger than 58% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The returns for 2018–2022 all give Monrovia as port of registry.

Its 5,409 t of CO₂ for 2022 is 25% below the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 529.3 kg CO₂, 27% above the type median of 415.9 kg. It logged 1,067 hours at sea against a median of 1,731 hours for its type that year. 19.5% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2018 (31,067 t) and the lowest 2022 (5,409 t). Its efficiency percentile within the type went from 65 in 2018 to 43 in 2022 (lower is more efficient).

Efficiency against its own type2022

Position 769 of 1,771 qualifying oil tankers by EEOI, at the 43rd percentile. The dashed line is the type median, 8.0; this vessel reported 7.4.

EEOI divides emissions by transport work, which for this vessel and year was 729,997,301 tonne-miles over 10,220 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 82.6% lower than in 2018, for EU/EEA voyages only.

From 2021 to 2022, emissions fell 75.3% while distance sailed fell 74.8%and CO₂ per nautical mile fell 1.8%.That points mainly to how much the vessel sailed, rather than the other.
